AsiaRC, To be truly honest, I don't care for crowd cheers or pride, or even for breaking a 10K toy, (even never being close to be rich). My greatest fear for flying jets or any high performance airplane is a high energy impact, or debris hitting something or someone, not to mention the fire possibility. I believe that most people think this way... anyway, I always been a advocate for using FS as a training tool, however it cannot teach you to fly under real world pressure, as cited above.

Best regards, Enrique
